WHEEL FOR FINISHING HEELS 0F BOOTS 0R SHOES.

Application led February 19, 1913.

Specification of Letters Patent.

Patented J all. 20, 1914.

Serial No. 749,293.

To all whom it may concern:

Be it known that I, CARL A. MA'rsoN, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented new and useful Improvements in iVheels for Finishing Heels of Boots or Shoes, of which the following is a specification.

This invention relates to an improved wheel for finishing the heels of boots and shoes, the same being particularly adapted to apply wax to the edges of the heels of boots and shoes and to burnish or polish the surface of the edges of the boot or shoe heel which is applied to it.

It is also the object of this invention to provide a wheel for finishing the heels of boots and shoes which shall have a yielding periphery so that it may accommodate itself to heels varying in cross sectional contour of the edges.

The invention, therefore, consists in a wheel formed as hereinafter described and particularly as set forth in the claims.

Referring to the drawings: Figure l is a plan of a portion of a machine for wax finishing the edges of the heels of boots and shoes showing my improved heel finishing wheel attached thereto. Fig. 2 is a sectional elevation taken on line 2-2 of Fig. 1. Fig. 3 is a side elevation of a modified form of my invention. Fig. 4; is a sectional elevation of a portion of a modified form of my improved heel finishing wheel.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, referring to Figs. 1 and 2, 5 is the frame of a machine in which is journaled a shaft 6 to which a rotary motion is imparted by means of a pulley 7. To the front end of said shaft is fastened my improved heel finishing wheel 8. Saidwheel consists of a rim 9 and a body portion 10 formed of yielding resilient material, such as rubber. The shaft 6 is reduced in diameter at its forward end as at 11, thus forming a shoulder 12, and upon this reduced portion 11 is located a clamp ring 13 which bears against the shoulder 12. The body portion of the wheel 8 bears against this clamp ring 13 and against its opposite face another clamping ring 14 is provided which has screw-threaded engagement with the reduced portion 11 of the shaft 6. Said clamping ring 14 is locked in position by a locknut 15. Thus it will be seen that the wheel 1s firmly clamped to the shaft 6 and will rotate with it.

A helical member 1G is embedded in the yielding material of the rim 9 and this helical member' is composed, preferably, of metal and is of a form such as that illustrated in Flg. 2, the same consisting of a strip of material, such as metal, which is hard relatively to the yielding material of which the rim 9 is composed. The helical member 1G is embedded in the rim S) in such a manner as to form a portion of the periphery of said wheel and of its work rubbing face. IVhile it is evident that the rim may be made of yielding material with the helical member embedded therein and the body portion of the wheel made of rigid or unyielding ma terial, still I prefer to mold the rim and body portion of the wheel of yielding material for the reason that when the wheel is in use the periphery will yield to accommodate itself to varying contours of the edge of the heel and the wheel will also yield in its body portion either to pressure brought to bear thereon by the operator, or, when it has a body portion of yielding material, such as rubber, the wheel will tip slightly laterally to accommodate itself to the varying positions in which the heel may be held by the operator. Thus the wheel will automatically accommodate itself, on account of its construction, to the different contours of heel edges and also to the different positions in which the heels may be held by the operator, so that it does not necessitate such a skilful handling of the shoe in order to produce a finely finished product, as would be the case if the wheel were made without the yielding body port-ion in addition to the yielding rim.

In Fig. 3 I have illustrated a form of my invention consisting of a wheel 17 which has a rim 18 formed of yielding material, preferably rubber', and in this form a plurality of strips of material 19, 20, and 21 are employed, each of said strips forming a helical coil, said coils being embedded in the rim and extending entirely around and forming a portion of the periphery of said wheel. By thus utilizing a plurality of said strips, each forming a helix, with a convolution of each of said coils located between convolutions of another of said coils, as illustrated in Fig. 3, a steeper pitch is obtained upon the helical member and 'thus the action of said helical member upon the heel is made more efficient, it being understood that it is desirable to polish the heel by the helical member in a direction extending circumferentially around the -heel and also to act upon the fibers of the leather Vto rub them lengthwise of the edge of the heel or from the heel seat toward the top lift of the heel, and this combined longitudinal and circumferential action will be more pronounced as the angle of the helical member is increased.

In the form of my invention illustrated in Figs. l and 2 a single helical member is used, while in that illustrated in Fig. 3 three helical members are used.

In the form of my invention illustrated in Figs. 1, 2 and 3 a flat strip of material is used, preferably o-f greater depth than its thickness.

In Fig. 4 I have illustrated a form of my invention in which a round wire is used for the helical member. In this form of my invention 22 is the helical member which is shown embedded in a rim 23 connected to a body portion 24.

A convenient and practical way of manufacturing the helical member illustrated in Figs. l and 2 and the plurality of helical members illustrated in Fig. 3 is to take a tube of the proper thickness and cut the helical members therefrom in a lathe. After said helical members have been thus formed, the convex contour may be obtained by turning said helical members in a lathe, the same being held firmly clamped in position while being turned. In the form of my invention illustrated in Fig. 4, where a wire is used for the helical member, the same may be coiled upon a suitable form while the form is being rotated on a lathe.

The general operation of the device hereinbefore described is as follows: The heel of the shoe is held against the periphery of the wheel which is rotated by the shaft 6 and pulley 7 and said shoe is held substantially in the position illustrated in dotted lines in Fig. 2. The shoe is tipped to bring different portions of the periphery of the edge of the heel into contact with the periphery of the finishing wheel in a manner well known to those skilled in this art. After the wax has been applied by said wheel the edge of the heel is still further polished, burnished and finished by sub-- mitting the same tothe action of what is known as a padding roll and subsequently to that, the edge of the heel is subjected to the action of a polishing brush, all of the latter operations being well known to those skilled in this art.

The rubber located between the different convolutions of the helical coil acts to im-.

also prevents any of the wax from passing through from the periphery of the wheel toward the interior or central portion thereof.

No means for feeding waX to the periphery of the work rubbing wheel hereinbefore described is shown or described in the foregoing specification, but any suitable means may be employed, such, for instance, as

holding a piece of wax against the edge of the wheel or feeding liquid wax to the wheel or allo-wing the wheel to run in a wax pot of melted wax, as described and shown in an application Serial No. 734,507, filed December 2, 1912, by me. Any practical means for supplying waX evenly over the surface of the wheel may be utilized and different means for doing this are well known to those skilled in this art.

I-Iaving thus described my invention, what I claim and desire by Letters Patent to secure is:

l. A wheel for finishing heels having a peripheral rim of yielding material and a helical member embedded in said rim.

2. A wheel for finishing heels having a peripheral rim of rubber and a helical member embedded in said rim.

3. A wheel for finishing heels having, in combination, a peripheral rim of yielding material and a strip of material forming a helical member embedded in said rim and constituting a portion of the periphery of said wheel.

4. A wheel for finishing heels having, in combination. a peripheral rim of yielding material and a strip of material forming a helical member embedded in said yielding material and constituting a portion of the periphery of said wheel.

5. A wheel for finishing heels formed of yielding material embodying in its construction a rim and a strip of material forming a helical member embedded in said rim and constituting a portion of the periphery thereof.

6. A wheel for finishing heels formed of yielding material embodying in its construction a rim and a body portion and astrip of material forming a helical member embedded in said rim and constituting a portion of the periphery thereof, in combination with a shaft, and means to clamp said body portion of said wheel to said shaft.

7. A wheel for 'nishing heels having a peripheral rim of yielding material and a plurality of flexible coils of relatively hard material embedded in said rim and forming a part of the periphery of said wheel.

8. A wheel for finishing heels having a peripheral rim of yielding material and a plurality of coils Vof relatively hard material embedded in said rim and forming a portion of the periphery of said wheel, said coils extending entirely around the periphpart a fine finish to the edge of the heel and l ery of said wheel.

tending entirely around and forming a portion ol the periphery of said Wheel, a eenvolution of each of said coils being located between eonvolutions of another of said coils.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
